Patent DE-4105855-A1 (DE)
Inventor: BOEHLER ERNST DR ING
IPC: B01J8/20
Filed: 1991-02-25
Abstract: The basis of the invention is the problem of combining, by means of a suitable process for the anaerobic treatment of water, the advantages of the vertical tube reactors having a narrow residence time spectrum with low overall height of the apparatus and low costs. The individual part-steps of the denitrification are to proceed undisturbed individually and successively. According to the invention, the raw water (1) to be treated is passed via at least two fluidised bed reactors (3) connected one after the other and in the operating state is transported, with support material overgrown by biomass, from each reactor stage into the subsequent reactor stage. This support material is passed with the water stream leaving the last reactor into a separation unit (7) from which the separated support material is returned into the first reactor stage (3a). Depending on the pressure drop  DELTA p in the individual reactor stages (3), the water to be treated can be passed via reactor stages (3a, 3b ...) staggered in height. <IMAGE>

Abstract: The drive hub for a vehicle, particularly a bicycle, comprises a hub axle 1, a hub sleeve 9 adapted to rotate in relation to the hub axle 1 and a driver 13 mounted to rotate on the hub axle 1. The driver 13 drives the hub sleeve 9 through a friction gear 17 of which the first toroidal disc 25 is rotationally rigidly connected to the hub axle 1, of which the second toroidal disc 27 is connected to the driver 13 via a ratchet free wheel coupling 23 and drives the friction wheel carrier 43 which is provided with a plurality of friction wheels 35 and which is, in force-locking manner, connected to the hub sleeve 9 via an expanding coupling 20. The infinitely adjustable transmission ratio of the friction gear 17 is controlled from within the hub axle 1 via a linkage 53 which, via a coupling ring 47, entrains the pivotally mounted lever  39c of the pivot frames of the friction wheels 35. The system's own transmission of the friction gear 17 from the driver 13 to the friction wheel carrier 43 downwards can be compensated by rotary speed increasing measures both at the chain drive and also within the friction gear 17 by asymmetrical disposition of the toroidal zones.

Title: Illumination for microscope used in surgical operations - has deflecting mirror above objective lens which is positioned laterally depending on axial position of eyepiece lenses
Inventor: MUELLER WERNER DR
IPC: A61F9/008
Filed: 1992-05-06
Abstract: The illumination source for a microscope used in surgical operations is located away from its optical axis with a mirror-type element on this axis above the main objective lens to deflect the light beam onto the target. The eyepieces of the microscope above this deflector are stereoscopic. A manual or motorised mechanism moves the deflector laterally above the objective so that the illumination can be varied. The mechanism uses a position sensor to give a continuous evaluation of deflector position. This is linked to the axial movement of the eyepieces lenses when the magnification is increased. A second example uses two deflecting mirrors, one fixed off centre to the optical axis and one variable in position. ADVANTAGE - Illumination of target varies with magnification through eyepieces.
